The combination of mammography, regular breast exams by your health care professional, and being aware of changes in your breasts may be the best way to find breast cancer early, when it is more easily treated. The American College of Obstetricians and Gynecologists recommends that women begin having mammograms to screen for breast cancer every year beginning at age 40 years.
